Patent CA-2143467-A1 (CA)
Inventor: KACZMARCZYK EDWARD T
IPC: E02F3/627
Filed: 1995-02-27
Abstract: A tractor-mounted loader includes a yoke member having legs joined by a bight member that carries a latch that is L-shaped in cross section and is pivotally mounted for movement between a closed position, wherein a first leg of the latch extends generally horizontally above and is engaged with a front-end weight bracket of the tractor carrying the loader, and an open position wherein the first leg is located in a generally upright position forwardly of the bracket.  A control rod extends along one of the legs of the yoke member and has its forward end connected to the latch so that rearward and forward shifting of the rod respectively moves the latch to and from its closed position.  A cylindrical lock member is adjustably threaded onto the rear end of the rod and is received for movement along a slot provided in the a rear portion of the one yoke member leg and is dimensioned for fitting closely in an enlarged rear end portion of the slot to establish a locked condition in the rod which corresponds to the closed position of the latch.  A necked down intermediate section of the lock member is movable into register with the slot to permit the latch rod to be moved forwardly to place the latch in its open position.

Title: Increasing the relative motion of a screen deck
Inventor: LOWER WILLIAM E
IPC: B07B1/38
Filed: 1993-10-05
Abstract: The screening efficiency of a gyratory screening machine (10), of the type having a moving base (14), is significantly in-creased by mounting to the base a spring/mass system (66, 64) which is tuned so that operation of the machine drive (19) pro-duces amplified movement of the mass (64) along at least one of two perpendicular axes on which the base moves. Movement of the mass (64) reduces the net force on the base along the axis on which the mass oscillates. The reaction force of the machine drive (19) on the base along the other of the two perpendicular axes may be offset by a rotary counterbalance (62) operated by the drive. Movement of the base relative to the ground (15) is thereby reduced, and movement of the screen deck relative to ground (15) is increased. This both increases the effectiveness of the screening motion and decreases the total reaction force transmitted through the base.

Title: Multiple-strategy crash discrimination system
Inventor: GIOUTSOS TONY
IPC: B60R21/01
Filed: 1994-03-30
Abstract: A system (10) and method for actuating a vehicle air bag (38) uses an optical detector (12) to generate an output (22) representative of tbe distance between a vehicle occupant and a fixed structure within the vehicle. The output (22) is subsequently used by a signal processor/discrimination unit (26) to generate data representative of actual occupant conditions, such as transitory occupant position, velocity and/or acceleration. The occupant condition data is used to select the temporally optimal one of a plurality of different predetermined parameter-based crash discrimination strategies (R,S,T,X,Y,Z;), and perhaps further used as a decisional criterion in at least one strategy. Each strategy employs different decisional criteria to provide a different range of actual times to fire. The different decisional criteria of the available strategies may be the result of uniquely-different parameter-based crash discrimination or otherwise-identical parameter-based algorithms employing different thresholds, or both. The air bag is actuated when the decisional criteria of the selected strategy are satisfied to generate an actual time to fire. The present system and method thus optimize crash discrimination analysis by customizing the analysis in real time to match actual rather than assumed occupant conditions.
